I need to start practicing as well. Some tips I've learned while researching what I need to do:
For not drinking with meals: Don't even make yourself something to drink until after you've finished eating. I've even thought about not making a drink until I'm done cleaning the kitchen after a meal. That gives me more time to keep busy and it won't seem like such a long time to wait for a drink.
For eating smaller bites: Purchase toddler utensils or Bariatric utensils (adult sized handles with smaller ends - available on Amazon). Also purchase small plates and bowls or Portion Control ones. I really like the ones with circles on them so you can measure your food on your plate in secret so you don't have to announce to the world you're monitoring your portions.
For chewing slowly: Cut your food into small bites (but not all at once!), put one bit in your mouth, set your utensil down, sit on your hands. Chew, chew, chew, chew, chew, chew, and chew some more. Then just sit a minute a take a deep breath, then get another bite. DON'T EAT DISTRACTED - This will be my biggest challenge, I'm the multi-tasking queen.
To break the gulping Water habit: Don't use a straw (my addiction!), barely open your lips and let the water drip in. Do this throughout the day, don't wait until you're thirsty to drink.
I made myself a pact that I would start practicing on July 1, but now that I've typed this all out I might as well start tonight!
Your hospital and mine must be reading the same manual, mine says they will tell me after July 2nd, I believe you can make 100 lbs down and still be upright and smiling! My personal goal weight is 150 pounds down, odd but my nurse practioner Valeria and I came to the same figure independently. You do yours , I'll do mine and someday we will dance👭in the sunlight☀together! we can do it, I know we can do it!
